Specification of Letters Patent.

Application filed April 1, 1905. Seria1No. 253,279.

ment of the barrel.

A further object of my invention is to provide an improved lock systemwhereby a more effective locking is secured.

A further object of the invention is to provide a detachable orremovable'hammer-lock wherein the lock and cover-plates and the guardare made of a single piece, whereby the device may be easily and readilyremoved for cleaning or other purposes. Said device is protected bymeans of a stock-connecting piece connecting the breech to the stock andforming another feature of my invention.

These and other objects are attained by the improved construction,arrangement, and combination of parts more fully described hereinafter,reference being hand to the accompanying drawings, the different viewsof which will now be described in de,

tail.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection through the center line of the gun. Fig. 2 is a verticallongitudinal section passing through one of the hammer-locks. Fig. 3shows the coverplate with the complete hammer-lock. Fig. 4 is a top planview of the cover-plate with the parts of the lock removed. Fig. 5 is afront elevation of said plate with the hammers and other lock parts.Fig. 6 is a front elevation of the plate with the lock parts removed.Fig. 7 is a cross-sectional view of the lower portion of the breech,showing the arrangement of the hammer-locks therein. Fig. 8 is a topplan view of the stock-connecting piece. Fig. 9 is a front elevation ofsame. Fig. 10 is a side elevation of a portion of the gun, showing themeans for securing the barrel on both sides. Fig. 11 shows a top planview of the barrels. Fig. 12 is a vertical longitudinal section throughthe breech, showing the arrangement of the improved-lock system; andFig. 13 is a cross section on line a b of Fig.12.

Likenumerals refer to out all the views. v

Referring particularly to the drawings, 1 represents thestock-connecting piece secured to the breech 2'by the-screw3 and tothestock by means of a projection 4- and screws 5 and 6, extendingthrough the upper like parts throughi Patented J an. 16 1190.6,

extension of the breech. Arranged within the recessed portion of thestock-connecting piece 1 is the trigger-plate '7, with-the triggers 8and 9, the sears 10, and the spring 11. The trigger-guard-12 is securedto the plate 7 at its forward end by meansof the screw 14 and at itsrearward end by means of its attachinghook 15. Th'ecover-plate 13 of thebreech is made one with upwardly-extending I plates '16 16.- r 1 Theparts of the locks (hammers 17, levers I 18, and mainsprings 19) arearranged on'the outer sides of the plates 16 16, the hammers 17 andlevers 18 being pivoted on pins 20, 21, 22, and 23, respectively. Thehammers 17 are held in operativeposition through the action of sears 10engaging notches 24', said sears being pivoted on a pin 25, arranged ina suitable projection 26. The triggers 8 and 9 are moved in slots 27 ofthe trigger-plate 7.

The operative position of the parts of the lock is shown in full lines,while the inoperative position is shown in dotted lines.

When the barrel of the gun is lowered after the disengagement of thelocking-bolts, (he'reinafter described) the forward end of the levers-18will be engaged by a projection of the tongue piece (not shown) andlowered by the same, so that said levers are caused to bring the hammers17 into their operative position.

The gun is taken to pieces as follows: The lock parts are first broughtinto operative position, and after having removed the barrel and thetongue-piece and unscrewed the screw 28 from the cover-plate and thescrew 29 from the stock-connecting piece the entire mechanism of the gunmay be easily removed by pulling on the trigger guard, whereby thebreech may be easily cleaned from the interior.

Referring more particularly to Figs. 10 to 13, 30 indicates thethumb-lever operating the bolt of the locking system and provided withthe downwardly-extending pin 31. The upper end of said lever has a smallpin or projection 32, which actuates the upper bolt 33 .the several lockparts, and means for when the thumb-lever is rotated. The lower end ofthe pin 31 has a laterally-projecting arm 34, carrying anupwardly-extending pin 35, engaging a downwardly-extending fork portion36 of the lower or main locking-bolt 37, whereby the latter is alsoactuated when the thumb-lever 30 is rotated. The lockingbolt 37 is-arranged over the plane of the breech portion on which rest the barrelsof the gun when the latter is closed, said locking-bolt snapping overthe rearwardly-extending fastening-hook 38, whereby a more effectivelocking is secured, as the lever-arm (distance between the locking-boltand the hinge 39) of the resistance is thereby increased.

A further arrangement for securing the barrels on the breech consists inproviding the barrels on both sides with extensions 40 40, engagingcorrespondin recesses 41 in the breech when the gun is in t e lockedposition. Thus any lateral movement of-the barrels is effectivelyavoided.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a drop-down gun, the combination with the breech and the stock, ofa stock-connecting piece, removably secured to said breech and stock, atrigger and breech coverplate made of a sin le plece, a tri ger-guard,means for removab y attaching t e latter to said trigger-plate, vertically-proj ecting plates on said coverplate, pivot-pins on saidvertically-projecting plates for the reception of locking the barrels onthe breech, substantially as set forth.

2. In a drop-down gun, the combination with the breech and the stock, ofa stock-connecting piece removably secured to said breech and stock, asuitable recess provided in said stock-connecting piece, a trigger-platearranged within the recess of said stock-connecting piece together withthe triggers, sears and springs, a trigger-guard removably attached tosaid tri ger-plate, a breech-covering plate made 0 a single piece withthe trigger plate, upwardly extending projections on said cover-plateand made one with the latter, pivot-pins on said projections for thereception of the several lock parts, and

means for locking the barrels of the gun on the breech, substantially asset forth.

3. In a drop-down gun, the combination with the breech and the stock, aconnecting piece between the same, and a suitable recess in saidconnecting-piece, of a tri ger and breech cover-plate made of a sing epiece, said trigger and breech cover-plate carrying the several parts ofthe lock housed partially within the recessed stock-connecting piece andpartially within the forward end of the breech, substantially as setforth.

4. In a drop-down gun, the combination with the breech and stock, asuitably-shaped connecting-piece between the same, a trigger and breechcover-plate made of a single piece and carrying all the parts of thegun-locks; of the thumb-lever of the locking system, thedownwardly-projecting pivot-pin of the same, an upper projection on thethumb-lever, engaging the upper locking-bolt, a lower projectionengaging the lower locking-bolt arranged over the barrel-fastening, arearward extension on the latter engaged by said lower locking-bolt, andmeans for preventing the lateral movements of the barrels in any case,substantially as set forth.

5. In a drop-down gun, the combination with the breech and stock, asuitably-shaped connecting-piece between the same, a trigger and breechcover-plate made of a single plece and carrying all the parts of thegun-locks; of the thumb-lever of the locking system, thedownwardly-projecting pivot-pin of the same, an upper projection on thethumb-lever, engaging the upper locking-bolt, a lower projectionengaging the lower locking-bolt arranged over t e barrel-fastening, arearward extension on the latter engaged by said lower locking-bolt,rearward extensions on both sides of the barrels, and correspondingrecesses, on the sides of the breech, adapted to be enga ed by saidextensions when the gun is in t e locked position, substantially as setforth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CARL LOHSE.
